Patente d May 25, 1943 UNITED STATES PATENT OFFICE RING TRAVELER MauriceLee Bolton,

This invention relates to ring travelers of the vertical type foremployment in spinning or twisting.

The device is primarily for use in spinning and twisting fine wire ofsteel, copper, brass and similar material, although the same couldreadily be used in connection with the spinning and twisting of threador yarn.

Ring travelers heretofore in use are not adapted for use in the spinningand twisting of wire and are objectionable, if usable at all, due to theformation of spirals or kinks in the wire as it travels from the guiderolls or guide eye and under the traveler head to the bobbin or spool onwhich the wire is being wound.

The formation of objectionable kinks or spirals are avoided by the useof the present device, due to the fact that practically the only bendmade in the wire or material during its passage from the feed rolls orguide eye to the finished wound bobbin is one substantially in the formof an are when the wire passes downwardly through the opening in thehead of the traveler and. out through the opening in the shank thereof;this rather than around and under the head. of the traveler, asheretofore, and then ,to the bobbin or spool.

Difiiculty in winding and twisting with kinks or spirals in the materialis thereby avoided Also by the use of the present traveler a moreupright position is maintained during the revolution of the traveleraround the ring than where the wire or thread or yarn passes beneath thehead and around one edge, as heretofore.

In the present invention there are no sharp bends or turns whatsoever inthe material as in travelers heretofore in use.

In travelers heretofore in use, the traveler binds on the ring, beingcanted in operation, but with the present traveler it is maintained inan upright position during its travel around the ring and all canting orbinding on the ring is avoided, thereby saving wear and tear on both thering and traveler.

Another object of the invention is the provision of ring travelers whichdo not require frequent replacement and which are capable of long usewithout diminishing in efficiency or effectiveness, which travelsmoothly and evenly and without vibration or jerkiness, which maintainsthe tension on the thread even and smooth and at the proper anddesirable degree, and cause no variation or unevenness in the twist ofthe yarn and which eliminate objectionable strains under tension due tothe formation of or cramping or Philadelphia, Pa., assignor to U. S.King Traveler 00., poration of Rhode Island Application December 11,1942, Serial No. 468,717 4 Claims. '(Cl. 57-125) Providence, R. I., acorkinks or spirals in the material in its passage through the traveler.

Another object of the invention is to avoid excessive friction orcramping of the traveler in its course around the ring occasioned bypassing the thread beneath the traveler, as heretofore, whereby thelatter is tilted bringing it in contact with the ring at an anglethereby causing wear and tear on both the traveler and ring.

It will be seen, therefore, that in the use of the present traveler allobjectionable sharp bends of the material is avoided such as are presentin the previous travelers.

To the attainment of the foregoing and other objects which will appearas the description proceeds, reference may be had to the accompanyingdrawing, in which:

Fig. 1 is a perspective view of a twister ring showing my novel ringtraveler in operating position thereon;

Fig. 2 is a sectional view of eler thereon;

Fig. 3 is a perspective view of the ring traveler; and

Fig. 4 is a sectional view on the line 4-5 of Fig. 1.

As shown, I0 is a vertical twister ring with the ring traveler H mountedin operative position thereon.

The traveler is formed from a metallic blank and comprises a verticalshank l2 formed with a head or horn portion l3 with a downwardlyinclined lip portion I4. Substantially centrally of the head or hornportion 13 a hole or opening I5 is provided through which the wire oryarn I8 first passes from the feed roll or guide eye (not shown) in asubstantially straight line and thence toward the spindle or spoolthrough the hole or opening [9 in the shank H. Formed upon the lower endof the shank and integral therewith is a foot portion l6 having anupturned portion or lip H.

The fine wire, thread, filament, yarn, strand or other material l8extends downwardly through the hole 15 and thence through the groove orguide 20 formed on the inner face of the traveler and connecting the twoopenings out through the hole 19 to the bobbin or spool.

It will be observed that due to the location and arrangement of theholes l5 and I9 relative to each other, the material will pass from theroll or guide eye to the bobbin or spool with no sharp bends, and thatthe traveler will move in a circular path around the ring without anycanting binding of the traveler on the the ring with travring and thusany grooving, excessive heating, or other disadvantage resulting fromfrictional contact of the traveler with the ring are avoided, and thematerial is maintained remote or away from the face of the ring l0.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent of the United States is:

1. A traveler for vertical twister rings comprising a vertical shank, alip integral with the lower end of the shank, a head portion integralwith the upper end of the shank, said head and shank portions eachhaving an opening therethrough through which the material being twistedand Wound is passed.

2. A traveler for vertical twister rings comprising a vertical shank, alip integral with the lower end of the shank, a head portion integralwith the upper portion of the shank, an opening formed in the headformed in the shank portion, the openings being so spaced and arrangedwith relation to each other that the material being twisted passesthrough the opening in the head in a substanportion and an opening guidefor the material from one opening to the I other.

4. A traveler for vertical twister rings comprising a vertical shank, alip integral with the lower end of the shank, a head portion integralwith the upper end of the shank, means in the shape of an opening formedin said head, and means in the shape of an opening formed in the shank,said means cooperating with each other to permit the passage of thematerial being twisted MAURICE LEE BOLTON.
